About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X225SU
The AirTAC MBLC63X225SU is a double-acting, 63 mm bore aluminum mini cylinder engineered for a 225 mm stroke. It delivers robust linear thrust, pushing with 1558 N and pulling with 1457 N at 0.5 MPa. Unlike the base MBL series, this variant features a screw-adjustable pneumatic cushion at both ends, allowing you to fine-tune end-of-stroke deceleration to match heavy loads and high cycling speeds, thereby protecting the end covers from impact damage.
This configuration includes a built-in magnet (S) for compatibility with AirTAC CMSG reed and DMSG or EMSG electronic sensor switches to confirm rod position. The U designation specifies a rigid flat-end back cover for straightforward mounting. It utilizes a G1/4 port, a Ø16 carbon-steel rod with 20 µm hard-chrome plating, and a heterogeneous two-way grease-retaining piston seal within a riveted rolling-packed aluminum barrel for compact, lightweight durability.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X225SU Is Used
Injection Mold Ejector
Drives a 225 mm ejection stroke on a mid-size plastic injection molding machine, using the 1558 N push force to clear heavy parts while the adjustable cushion prevents harsh stopping impacts.
Pallet Transfer Brake
Acts as a stopping gate for heavy pallets on a packaging conveyor, relying on the 63 mm bore's 318 kgf peak capacity and tunable air cushions to absorb the momentum of arriving loads smoothly.
PCB Shuttle Actuator
Moves populated PCB trays between SMT ovens, where the built-in magnet triggers DMSG solid-state sensors for precise end-position confirmation and the cushion protects delicate solder joints.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X225SU the Right Cylinder?
At 63 mm, this bore provides the highest standard thrust in the MBL family, yielding 318 kgf maximum theoretical force at 1.0 MPa. If you need to reduce mass and air consumption, stepping down to the 50 mm bore offers 981 N push at 0.5 MPa. Stepping up is not an option within this mini-cylinder range, so for even greater loads, you must transition to a larger ISO 15552 profile cylinder. Choose this MBLC cushioned version over the fixed-bumper MBL when your 225 mm stroke operates at high velocities or shifts heavy masses. Note that a plain double-acting cylinder drifts when air is removed; the cushions only decelerate near the ends and do not lock the rod. For position holding without live air, integrate an external rod lock.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (LB / FA / SDB) and back cover (CA pivot / U flat-end).
- check Installation by qualified personnel per AirTAC docs.
Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X225SU FAQ
This 63 mm bore cylinder uses a G1/4 port and a Ø16 mm rod with an M14x1.5 thread. It generates 1558 N push and 1457 N pull at 0.5 MPa, 2181 N push at 0.7 MPa, and a maximum theoretical force of 318 kgf at 1.0 MPa.
The MBLC63X225SU features a screw-tunable needle at both ends that traps exhaust air to decelerate the piston smoothly before it hits the cover. You adjust the needle to match your load and speed, which reduces impact, noise, and vibration; it is a deceleration device, not a load lock or brake.
